ABSTRACT
Planting trees in agricultural land on community forest and agroforestry systems is expected to
improve the sustainability of the landscape from the ecological, social and economic aspects.
Land management was a major factor that determines the decision-making process to select the
type of plants. The existence of trees in community forest can maintain and recover land
productivity as well as provide income for farmer. Net present value (NPV) analysis can be used
to assess of the economic benefits of trees within a certain time. The purpose of this study were
to evaluate the economic benefits of community forest system (Paraserienthes and teak)
compared to annual crops (maize and onion), and to analyze which system is the best in terms
of economic and ecological aspects. This research was conducted in Malang District which is
the center of community forest in East Java. The survey was conducted by purposive sampling
method to obtain spesific information related to production cost and income from farmers who
actually manage community forest system. Totally 20 farmers were selected in research area.
The result showed that the average of population density in community forest was 1396 tree ha
77% of population was dominated by mild tree (WD 0.6-0.75 g cm-3) and 23% of light tree.
Total carbon stocks in teak community forest was quite higher than community forest of
Paraserienthes. Based on economic perspective, teak community forests had the highest NPV
value of Rp 643.514.720,- ha-130y-1, while Paraserienthes community forests was about 44%
lower (Rp 357.833.338,- ha-130y-1). The average of NPV value in community forests was higher
than annual crops. Community forests are more economically profitable than annual crops. In
ecological perspective, community forests can maintain and gradually improve land
productivity and soil fertility through litter input, prevent the loss of topsoil from runoff because
of the canopy cover, as well as increase carbon sequestration.
